Lane Keep Assist

[Riggo]

So just for fun with lane keep assist turned on, I sometimes let my hands off the wheel (when no one is ahead or behind me for several hundred yards) and see what the car will do. I've noticed on straight roads it does a pretty good job of gettng me back in my lane without me touching the wheel. However, if I do this on a curve the car will just head right off the road if I didn't intervene.

 

I guess I was hoping for the car to be able to drive itself (more or less) but really that's not the case at all, at least on curves. One day we'll get there!

 

I'm not really sure what the point of this post was, other to say that I want my car to be K.I.T.T. someday.

Patience, Michael.

When I took my hands off of the wheel to try that the car told me to put my hands back on the wheel.

I think that's why they filmed that Fusion driving off of the cliff. He was using Lane Assist on a curve. ;-)

 

It's a great feature, but its only a reminder to pay attention. I read an article the other day the Acura is coming out with a system in 2014 that will keep it hands free for up to nine seconds at a time, even ion curves (so they claim). All of what we are seeing with the Fusion is a taste of what the cars of the near future will all have.

It only works above certain speeds (40 maybe). Also, you have to make sure it can see the lines on the road. If it shows a white line on the display, it won't do anything. I see the white line on the display sometimes even when the lines on the road are perfectly clear.

Mine has problems when driving into the sun. I guess the reflection off the road is washing out the image. I suspect the same may happen at night on wet roads as well (not sure I'll ever find out, it doesn't rain in North TX :) )

Ours tells me to stop for a cup of coffee.

 

I scratched my head on lane keeping when I 1st used it because it only "yelled" at me. Later I found out that was the factory default was Alert only. I reset the properties to Both Alert+Aid, then finally to Aid only as I still didn't like it "yelling" at me. I'm gonna check it out on the curves.

It seems to work in very very slight curves but not more curved curves. Ha that didn't make any sense.

The advanced optics behind the rear view mirror read the white and yellow lines - if you go off the beaten path you will see that the green lines on the dash disappear -

Lane Keeping, BLIS, Adaptive Cruise Control, Park Assist, My Ford Touch, Navigation - if they start showing us what's over the next hill I'd lose my yen to travel.

All it needs now are machine guns, rocket launchers and a bullet proof shield in the back.

 

 

 

Sounds like a movie car doesnt it.

Can't tell if this is Ingot Silver or Oxford White.

Well, it can't be too rigid or you could never change lanes in the thing.

I was wondering, when you have a turn signal on and your switching lanes, does it intentionally not activate?

I was doing this the other day and intending to switch lanes and it yanked me back. Kind of freaked me out.

No really, I want to switch lanes!. ? How does it know besides the turn signal being on?

 

I found that dangerous and I turned it off immediately. I was on a major highway - I was confused...

The only way, besides pushing the button turning the function off, is to activate your turn signal when changing lanes. Which is what your supposed to do.

[smr2112]

That's what I'd expect. I was pretty sure I had the T/S on, but either I didn't have it on or it wasn't fully engaged yet.

I'm pretty good about that and that's why it surprised me. Going to have to test it again on a tamer road.

[fusionTX]

I only use it for road trips. I do not use it for everyday driving.

Turn your T/S on before you start changing lanes :)

 

BTW, when I tried this on the highway in a curse it corrected itself once but the 2nd time it crossed the white line. Had to turn the steering wheel all by myself .. :(

The turn signal needs to be past the detent into full signal, not the 3 blink mode for it to deactivate. It will let you override when changing lanes, but the first couple times it does make you go WHAT?

Yep, exactly my reaction and I may not have had the turn signal all the way down as it was a quickly lane change. Not sure.

But my brain did go "WHAT?" - just the that as I wasn't expecting it to happen.

 

I do especially like the Lane Keeping when I've had a few too many, it keeps me on the straight and narrow - literally ! :worship:

What will it do if you're having to change lanes quickly in an emergency maneuver without time to signal? I imagine it wouldn't be hard in that situation to overpower it.

 

Today is super windy, cross winds of about 20 MPH with 30+ MPH gusts. LKA did a great job of combatting the gusts and keeping me between the lines. Although, after awhile it recommended that I stop and rest. I guess the wandering because of the wind was enough to make it think I was sleepy.

 

I've found that on light colored concrete roads with white stripes it has trouble picking out the lines on a sunny day. On roads paved with tar it works much better. Many of our freeways are concrete and the new style concrete used the last few years is almost as white as snow. This makes the white stripes hard to see with human eyes on sunny days, little wonder the car struggles to see them.

[DeeCee]

Its not hard at all to over power it.

 

Yes it does give you the "time out for a rest message" if you wander a bit, either unintentionally or from cross winds.

 

About the only time I use it anymore is while traveling on the interstate highways.

No it's not hard to overpower in an evasive maneuver, but it will give you quite a scare in less obvious situations.

I had a situation where there was construction and lanes shifted, but they hadn't completely covered the old yellow line. As I gently shifted lanes to the left, my car thought the road kept going straight and attempted to guide me into the newly setup concrete barrier. The rumble was enough to frighten me and I quickly hit the turn signal instead of overpowering it.

 

I now disable it anytime I see construction.

I was once driving on one of the below grade freeways on a sunny day in late afternoon. The sun was at just an angle that the shadow of the railing along the top of the freeway left a gap of sunlight about 3 inches across, about 12 inches to the left of the lane markings. Since the sunlight strip was actually brighter than the real lane markings, the system was picking that up and giving me a hard time.

 

I don't know if it does, but the system certainly has the ability to determine if you input a fast enough or large enough steering wheel input (like an emergency maneuver) that it could disable itself before it tried to counter your input. It already knows the steering wheel angle and the input torque.

Great tip! I will keep this in mind!
